Named-entity recognition
gpt-5-mini
Instruction
Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

-
A.
Prandtl–Blasius boundary layer solution
The Prandtl–Blasius boundary layer solution is a classical analytical solution in fluid dynamics that describes the velocity profile of laminar flow over a flat plate near its surface.
-
B.
Prandtl boundary layer
The Prandtl boundary layer is a fundamental fluid mechanics concept describing the thin region near a solid surface where viscous effects dominate and velocity changes rapidly from zero at the wall to the free-stream value.
-
C.
The Theory of Homogeneous Turbulence
The Theory of Homogeneous Turbulence is a classic monograph in fluid dynamics that provides a rigorous mathematical treatment of statistically uniform turbulent flows.
-
D.
On the theories of the internal friction of fluids in motion
"On the theories of the internal friction of fluids in motion" is a foundational scientific paper by George Gabriel Stokes that established key principles of fluid dynamics and viscosity, leading to what is now known as the Navier–Stokes equations.
-
E.
Prandtl–Batchelor theorem
The Prandtl–Batchelor theorem is a result in fluid dynamics that characterizes the uniform vorticity distribution in regions of closed streamlines at high Reynolds numbers.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
